Features
Features common to many embedded applications, such as DMAs, various DRAM
controller interfaces, and on-chip memories, are integrated using advanced process
technologies.
The MCF5307 extends the legacy of Motorola’s 68K family by providing a compatible path
for 68K and ColdFire customers in which development tools and customer code can be
leveraged. In fact, customers moving from 68K to ColdFire can use code translation and
emulation tools that facilitate modifying 68K assembly code to the ColdFire architecture.
Based on the concept of variable-length RISC technology, the ColdFire family combines
the architectural simplicity of conventional 32-bit RISC with a memory-saving,
variable-length instruction set. In defining the ColdFire architecture for embedded
processing applications, a 68K-code compatible core combines performance advantages of
a RISC architecture with the optimum code density of a streamlined, variable-length
M68000 instruction set.
By using a variable-length instruction set architecture, embedded system designers using
ColdFire RISC processors enjoy significant advantages over conventional fixed-length
RISC architectures. The denser binary code for ColdFire processors consumes less memory
than many fixed-length instruction set RISC processors available. This improved code
density means more efficient system memory use for a given application and allows use of
slower, less costly memory to help achieve a target performance level.
The MCF5307 is the first standard product to implement the Version 3 ColdFire
microprocessor core. To reach higher levels of frequency and performance, numerous
enhancements were made to the V2 architecture. Most notable are a deeper instruction
pipeline, branch acceleration, and a unified cache, which together provide 75 (Dhrystone
2.1) MIPS at 90 MHz. Increasing the internal speed of the core also allows higher
performance while providing the system designer with an easy-to-use lower speed system
interface. The processor complex frequency is an integer multiple, 2 to 4 times, of the
external bus frequency. The core clock can be stopped to support a low-power mode.

Serial communication channels are provided by an I
C interface module and two
programmable full-duplex UARTs. Four channels of DMA allow for fast data transfer using
a programmable burst mode independent of processor execution. The two 16-bit
general-purpose multimode timers provide separate input and output signals. For system
protection, the processor includes a programmable 16-bit software watchdog timer. In
addition, common system functions such as chip selects, interrupt control, bus arbitration,
and an IEEE 1149.1 JTAG module are included. A sophisticated debug interface supports
background-debug mode plus real-time trace and debug with expanded flexibility of
on-chip breakpoint registers. This interface is present in all ColdFire standard products and
allows common emulator support across the entire family of microprocessors.
